Active surveillance for cardiac complications after major noncardiac surgery: implications on resource utilization and safety in high-risk patients

Abstract Background The 2022 ESC guidelines on cardiovascular assessment and management of patients undergoing noncardiac surgery recommend that high-risk patients should undergo active surveillance for cardiac complications, including perioperative myocardial infarction/injury (PMI), following major noncardiac surgery. Unfortunately, little is known about the resource use and safety of active surveillance compared to a control cohort (i.e. without active surveillance). Objective To quantify the impact of active surveillance for cardiac complications, by perioperative cardiac troponin (cTn) measurements and a systematic PMI work-up on working days, on resource usage and safety. Methods We did a retrospective comparison of non-randomised pre- vs post-implementation of an active surveillance program for cardiac complications in patients at elevated cardiovascular risk undergoing noncardiac surgery at two hospitals in Switzerland. The two cohorts' resource use and safety were compared. Resource use encompassed perioperative cTn measurements, ECGs, cardiac imaging, cardiology consultations as well as coronary angiography (CAG) and revascularisation procedures. Safety was assessed based on the number of "seemingly normal CAG" and complications arising from CAG and revascularisation procedures. Results A total of 13’147 patients, 10’346 in the active surveillance cohort and 2’805 in the standard-of-care (SOC) cohort, were eligible for this analysis. Patient characteristics between both cohorts were comparable (e.g. median age of 74 vs 73 and 44.8% vs 43% female, respectively). Patients in the active surveillance cohort underwent significantly more perioperative cTn measurements (86.4% vs 3.5%, respectively), postoperative ECGs (13.5% vs 5.7%), postoperative cardiac consultations (5.9% vs 2.4%), postoperative transthoracic echocardiogram (TTE) (7.5% vs 6.1%), postoperative myocardial perfusion imaging (MPI) (1.2% vs 0.6%), and postoperative CAG (0.8% vs 0.4%, all p <0.05). The increased resource use led to a substantial increase in detected cardiac complications within the first 48h after surgery: active surveillance 1’207 (12%) (95%CI 11%-12%) vs SOC 68 (2.4%) (95%CI 1.9%-3.1%). The active surveillance cohort generated an overall cardiac management cost of 236 Euros (95%CI 223–250) per patient vs 133 Euros (95%CI 110–160) per patient in the SOC cohort, resulting in an incremental cost for the active surveillance of 103 Euros (95%CI 110–160) per patient. Thereby the cost of detecting one additional cardiac complication within 48h was 989 Euros. Concerning safety, no significant differences in the number of "seemingly normal CAG" (6.4% vs 15%, p=0.1) and complications due to CAG and revascularisation (0.6% vs 5.1%, p=0.08) were observed. Conclusion The active surveillance for cardiac complications is safe when compared to a standard-of-care cohort while 989 Euros per additional detected cardiac complication seems reasonably priced.Resource-utilization tableOverview

DWI lesions after intracranial aneurysm treatment with contour or WEB-does the device matter?

In this study, we report our experience with the occurrence of diffusion-weighted imaging (DWI) lesions following aneurysm treatment with Woven EndoBridge (WEB) device and Contour Neurovascular System in elective settings. We compared both techniques in a retrospective single-center analysis, to investigate whether there are significant differences in the incidence of microemboli depending on the device used. Sixty-two cases treated with Contour were retrospectively compared with 84 WEB cases. Postinterventional MRI was performed in all patients within five days after the angiographic procedure. Only DWI lesions in the dependent vascular territory of the treated aneurysm were considered. Data on occurrence of DWI lesions, device implantation times as well as device change or repositions maneuvers were compared. A total of 146 patients were included in this study. Postinterventional DWI lesions were detected in 33 of the 62 (53.2%) Contour cases and in 36 of the 84 (42.8%) WEB cases with an average lesion number of 1.70 ± 3.45 in our WEB group and 1.68 ± 2.53 in our Contour cohort. Neither periinterventional device changes nor device reposition maneuvers had a significant impact on the occurrence of DWI lesions. Although four patients experienced transient neurological deterioration, the DWI lesions were not clinically relevant at the time of discharge, as the patients' NIHSS remained stable compared to the preintervention NIHSS in the entire cohort. There was no statistically significant difference between the implantation times of WEB and Contour, although Contour could be implanted slightly faster. Aneurysm treatment with WEB or Contour results in a comparable numbers of procedure-related DWI lesions. This effect was consistent after adjustment for other demographic or technical variables.

Association between blood microplastic levels and severity of extracranial artery stenosis

Microplastics (MPs) contamination raises concerns about their impact on human health, particularly cardiovascular diseases. This study investigated the blood MPs levels in patients with extracranial artery stenosis (ECAS) and their possible link to disease severity. 20 ECAS and 10 control patients were recruited. Blood samples, collected before the digital subtract angiography (DSA) procedure, were analyzed by pyrolysis–gas chromatography mass spectrometry (Py-GC/MS), laser direct infrared (LDIR) spectroscopy, and scanning electron microscopy (SEM). Demographic and clinical information was also examined. Strict quality controls were implemented to prevent contamination. MPs were detected by Py-GC/MS in all blood samples, with concentrations significantly higher in ECAS group compared to control (174.89 ± 24.95 vs 79.82 ± 31.73 μg/g, p < 0.001), and polyvinyl chloride (PVC) and polyamide 66 (PA66) were the most abundant among the detected polymers. Further analyses suggested that higher concentrations of MPs may be associated with more severe artery stenosis (p < 0.001). Compared with the normal group, ECAS group had a higher level of D-dimer (0.61 ± 0.6 μg/L vs 0.28 ± 0.09 μg/L, p < 0.05) and longer Thrombin Time (sec) (18.30 ± 3.43 μg/L vs 16.25 ± 1.74 μg/L, p < 0.05). Additionally, LDIR and SEM detected the shape and physical properties of the MPs. In this study, we revealed significant higher blood MPs levels in ECAS patients, with a notable correlation between MPs concentrations and arterial stenosis severity.

Designing and evaluating a mobile app to assist patients undergoing coronary angiography and assessing its impact on anxiety, stress levels, and self-care

BackgroundCoronary artery disease is one of the leading causes of death and disability worldwide. Coronary angiography is a diagnostic procedure used to detect atherosclerosis. Patients typically experience anxiety and stress before and during the angiography procedure. Furthermore, self-care ability is crucial following angiography.AimThis study aims to describe the design and evaluation of a mobile application focusing on stress, anxiety, and self-care abilities in patients undergoing coronary angiography.MethodThe researchers developed a mobile application for patients undergoing angiography. The application provides information about angiography and tips for enhancing self-care following the procedure. An interventional study was conducted on 70 patients admitted to the angiography ward in hospitals in Kerman, Iran, between 2022 and 2023. The participants were randomly divided into two groups: control and intervention. The interventional group received the intervention application the night before angiography. Two groups completed the Anxiety and Stress Questionnaire (DAS) and Kearney-Flescher Self-Care Survey before the intervention. The researchers used questionnaires that had been prepared and previously utilized in other studies. The two groups completed the anxiety and stress questionnaire within three to six hours and the self-care questionnaire one month after angiography. SPSS 15 software was used for data analysis, with a significance level set at 0.05.ResultsThe study found that the majority of participants were women. Before the study, there was no significant difference between the two groups in terms of anxiety, stress, and self-care scores. However, after the study, the intervention group showed a significant decrease in average anxiety and stress scores (p < 0.001). Additionally, compared to the control group, the intervention group demonstrated significant improvement in average self-care score (p < 0.001).ConclusionAccording to this study, AP can be effective in influencing the anxiety, stress levels, and self-care ability of patients who undergo coronary angiography. It can help to reduce stress and anxiety while increasing self-care. Instructive software is user-friendly, cost-effective, and can be recommended by nurses and doctors.

12391 When Pressure Drops, Consequences Rise: A Case Of Pituitary Apoplexy And Watershed Infarcts

Abstract Disclosure: D. Moreno Watashi: None. H.R. Alkaissi: None. M.B. Sharma: None. Introduction: Pituitary apoplexy (PA) results from sudden hemorrhaging and infarction of the pituitary gland, typically within a pituitary adenoma. The primary symptom is a sudden, severe headache, often followed by acute endocrine dysfunction, ophthalmoplegia and visual or neurological disturbances. Case Description: A 68-year-old male with a past medical history of hypertension presented to the emergency department with acute chest and upper back pain, beginning one day prior. No history of smoking, alcohol intake or drug use. Blood pressure (BP) on arrival was 180/95 mmHg. Initial labs revealed mild electrolyte abnormalities. Troponins were normal, but ECG showed diffuse T wave inversion and ST depression. CT angiography revealed a type B aortic dissection. He was managed in the critical care unit with continuous esmolol intravenous (IV) infusion and planned for endovascular repair. During his stay, he became disoriented and hypotensive. MRI from the brain incidentally discovered a pituitary macroadenoma measuring 2.9x2.2x3cm and recent infarcts, with a distribution concerning for hypoperfusion. Fundoscopy concerning for optic chiasm compression. Labs indicated secondary hypothyroidism and hypogonadism (TSH 0.3 uUI/ml, free T4 0.88 ng/dL, total testosterone 56.3 ng/dL). Neurosurgical intervention was deferred until after aortic repair. Endovascular aortic repair was performed with episodes of hypotension. Post-procedure, the patient developed fever (39.5°C) and worsening mental status. Head CT revealed an increased suprasellar extension of the pituitary macroadenoma and vasogenic edema, consistent with hemorrhage of the lesion. He was started on stress doses of hydrocortisone, levothyroxine 125mcg and managed conservatively due to a high surgical risk. Discussion: PA's extrinsic risk factors include angiographic procedures, endocrinological dynamic tests, anticoagulation therapy, exogenous estrogen administration, orthopedic and cardiac surgeries (due to BP fluctuations). The intrinsic risk factors are non-functioning adenomas, macroadenomas and suprasellar extension. Treatment is focused on immediate correction of endocrine derangements and relieving local compression. Stress dosage of corticosteroids should be administered IV as soon as the diagnosis is confirmed to prevent life-threatening corticotropic deficiency. Neurosurgical decompression via a transsphenoidal approach is the definitive therapy to relieve local compression with severe visual loss, obtundation or rapidly progressive course. The potential outcomes are based on the extent of hemorrhage, necrosis, and edema. PA should be treated as a medical emergency in the setting of hemodynamic changes from acute corticotropic deficiency and irreversible neurological damage from acute intracranial compression. The risk factors for PA should be known to assist in early diagnosis. Presentation: 6/1/2024

Incidence and Predictors of Early and Late Radial Artery Occlusion after Percutaneous Coronary Intervention and Coronary Angiography: A Systematic Review and Meta-Analysis

Introduction: Trans-radial access for coronary angiography and percutaneous coronary intervention (PCI) has gained popularity due to its advantages over the traditional transfemoral approach. However, radial artery occlusion (RAO) remains a common complication following trans-radial procedures. This study aimed to investigate the incidence of early and late RAO along with their risk factors. Methods: Six databases, Medline (Ovid), National Library of Medicine (MeSH), Cochrane Database of Systematic Reviews (Wiley), Embase, Scopus, and Global Index Medicus, were searched. The systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were extracted and analyzed. Using a random-effect model, the primary endpoint was the overall incidence of RAO after invasive coronary procedures. Subgroup analysis and meta-regression were also performed to identify possible predictors of RAO. Results: A total of 41 studies with 30,020 patients were included. The overall incidence of RAO was 13% (95% CI = 0.09–0.16). The incidence of early RAO (within 24 h) was 14% (95% CI = 0.10–0.18) in 26 studies, while the incidence of late RAO (after 24 h) was 10% (95% CI = 0.04–0.16) in 22 studies. The average incidence rates of early RAO in studies with catheter sizes of &lt;6 Fr, 6 Fr, and &gt;6 Fr were 9.8%, 9.4%, and 8.8%. The overall effect size of female gender as a predictor was 0.22 with a 95% CI of 0.00–0.44. Age was a potential predictor of early RAO (B = 0.000357; 95% CI = −0.015–0.0027, p: 0.006). Conclusions: This meta-analysis provides essential information on the incidence of early (14%) and late (10%) RAO following angiographic procedures. Additionally, our findings suggest that female sex and age are possible predictors of RAO. A larger catheter, especially (6 Fr) and hemostatic compression time &lt;90 min post-procedure, substantially reduced the incidence of RAO. The use of oral anticoagulation and the appropriate dosage of low-molecular-weight heparin (LMWH) does reduce RAO, but a comparison between them showed no statistical significance.

Comparison of radial artery occlusion between traditional radial access and distal radial access for coronary angiography and intervention: A prospective cohort study

BackgroundThe radial approach is now recommended as the default strategy in diagnostic coronary angiography and percutaneous coronary intervention. Radial artery occlusion (RAO) is the most common complication that limits subsequent angiographic procedures through this access. Recently, distal radial access (DRA) has been recommended as an alternative access site. Despite lower RAO rates in DRA in some recent clinical trials, concerns remain regarding possible complications and limitations due to the small size of the distal radial artery. ObjectiveThe present study aimed to compare traditional radial access (TRA) and DRA concerning RAO in percutaneous coronary procedures. MethodsIn the present prospective cohort study, percutaneous coronary procedures were performed via DRA or TRA in 2 study groups. All consecutive participants underwent DRA from September 2021 to March 2022 and TRA from April 2022 to June 2022. Ultrasonography was performed preprocedurally in the DRA group, and patients with small distal artery diameters (<2 mm) were excluded. The same 6-Fr sheaths and standard air-filled compression devices were used in both groups. The primary endpoint was RAO in ultrasound sonography on the first postprocedural day, and the secondary endpoints were the success rate, access time, angiography time, radial artery spasms, and vascular access complications. ResultsA total of 298 patients were assigned to the DRA group and 278 to the TRA group. The RAO rate was significantly higher in the TRA group than in the DRA group (10.1 % vs 0.9 %; P = 0.0001; OR, 0.08, 95 % CI, 0.01–0.27). The success rate was significantly higher in the TRA group (96 % vs 90.2 %; P = 0.009). Access crossovers were done on 12 patients (4.0 %) in the TRA group and 24 patients (9.8 %) in the DRA group (P < 0.001). The mean access time was significantly lower in the TRA group than in the DRA group (1.9 min vs 2.9 min; P < 0.001). The mean angiography time did not significantly differ between the groups (10.2 min in the TRA group vs 9.9 min in the DRA group). The rate of radial artery spasms was not significantly different between the 2 groups (13.8 % in the TRA group vs 14.5 % in the DRA group). The rates of access site hematoma (12.4 % vs 2.3 %; P < 0.001) and bleeding (10.7 % vs 4.1; P = 0.005) were significantly higher in the TRA group. ConclusionsDRA was safe and feasible with lower rates of RAO and access site complications than TRA. Thus, it could be used as an alternative approach in percutaneous coronary procedures. However, the trade-off for these advantages of DRA is an increase in cross-over rate, and a decrease in puncture success rate.

The effect of music therapy and breathing exercise on anxiety and pain in patients undergoing coronary angiography: A randomized controlled study.

For over 50 years, music therapy and breathing exercises have been widely utilized as interventions to help individuals cope with fatigue, stress and pain globally. To analyse the effects of music and breathing exercises on anxiety and pain in patients undergoing coronary angiography. This is a single-blind, randomized controlled trial. The sample comprised 165 patients: 55 in the control group, 55 in the breathing exercise group and 55 in the music therapy group. Patients in the music group listened to music during angiography, those in the breathing exercise group practised exercises 30 min before the procedure and the control group received standard treatment. Anxiety levels were assessed before and after the procedure, and pain levels were measured post-procedure. The Consolidated Standards of Reporting Trials (CONSORT) checklist for reporting randomized trials was used to guide reporting. Anxiety scores rose significantly in the control group from 33.9 ± 4.2 pre-angiography to 37.7 ± 4.9 post-angiography. Conversely, the breathing group's anxiety scores decreased from 34.3 ± 3.5 before angiography to 31.7 ± 1.5 after angiography, and the music group exhibited a reduction from 32.3 ± 3.6 to 30.8 ± 1.6. Post-angiography, the control group reported a mean pain score of 64 ± 0.8 mm, while the breathing and music groups had significantly lower scores of 35 ± 0.6 and 29 ± 0.8 mm, respectively. Statistical analysis showed a highly significant difference in pain scores between the intervention and control groups. This study provides support for the beneficial effects of employing breathing exercises and music in alleviating pain and anxiety during coronary angiography procedures. Integrating these findings into clinical practice could be significant for improving patients' pain experiences and anxiety, enhancing the tolerance of invasive medical procedures.

Standardizing X-Ray and Angiography Procedure Coding in Estonia: Validating TermX Through the Implementation of SNOMED CT.

The existence of multiple code systems and standards has highlighted the necessity for innovative solutions to bridge these discrepancies. This research investigates the utilisation of TermX to tackle the challenges of interoperability in radiology procedures, with a specific emphasis on angiography and X-ray modalities. The study produced a revised RadLex data model and mapping guide, designed to classify radiology services using TermX. In total, 380 concepts were required to comprehensively describe all 622 procedures examined. Our study demonstrates the effectiveness of TermX in simplifying the process of mapping between code systems, thus enabling more efficient analysis, and reporting of data.

Robotic spinal angiography: A single-center experience.

Robotic neurointervention enhances procedural precision, reduces radiation risk, and improves care access. Originally for interventional cardiology, the CorPath GRX platform has been used in neurointerventions. Recent studies highlight robotic cerebral angiography benefits, but information on spinal angiography is limited. While a new generation of robotic solutions is on the horizon, this series evaluates our experience with the CorPath GRX in spinal angiographic procedures, addressing a key gap in neurointerventional research. In this single-center retrospective case series, we analyzed 11 patients who underwent robotic-assisted diagnostic procedures with the CorPath GRX system from February 2022 to March 2023 at our institution. A descriptive synthesis was performed on the demographic, baseline, surgical, and postoperative data collected. The average age of the 11 patients was 54 ± 20.34 years, with six (54.55%) female. The mean body mass index was 29.58 ± 7.86, and 7 (63.64%) were non-smokers. Of the 11 procedures using the CorPath GRX system, four (36.36%) were partially converted to manual technique. General anesthesia was used in nine cases (81.82%), and right-side femoral access in ten (90.91%) patients. Mean fluoroscopy time was 24.81 ± 10.19 min, contrast dose 174.09 ± 57.31 mL, dose area product 472.23 ± 437.57 Gy·cm², and air kerma 2438.84 ± 2107.06 mGy. No robot-related complications and minimal procedure-related complications were reported. The CorPath GRX system, a robotic-assisted platform, has proven reliable and safe in spinal angiography, evidenced by its enhanced procedural accuracy and reduced radiation exposure for operators.

Mortality and postinterventional complications after ablative treatment of liver malignancies: A cohort study of 4374 patients

PurposeAblative therapies for primary and secondary liver malignancies are increasingly adopted in current guidelines. Nevertheless, surgical resection remains the gold standard in most curative therapy settings.Extensive studies on mortality and morbidity after ablative treatment of the liver are missing. We investigated complications and mortality after ablative treatment in a large, unselected study cohort. Materials and MethodsStandardized patient and treatment data in 4374 percutaneous and angiographic ablative procedures of the liver from the DRG-based hospital reimbursement system (diagnosis-related groups) of an academic hospital in Germany were retrospectively evaluated. We analyzed descriptive patient data, length of stay (LOS), pre-existing medical conditions, previous gastrointestinal surgeries, severe complications, and occurrence of death. ResultsTreatment of secondary liver malignancies constituted over two-thirds of all procedures (71%, n = 3053). The mean LOS was 4.1 ± 3.5 days. Severe complications were documented in 1.4% and in-house death in 0.2% of cases, significantly more often after treatment with chemoembolization of primary liver malignancies (p = 0.003; p = 0.000).Previous partial liver resection, partial bowel resection, and chronic renal failure were independent risk factors for the occurrence of severe complications. ConclusionSevere complications and in-hospital death are rare in the treatment of primary and secondary liver malignancies with percutaneous and angiographic procedures.They are a viable alternative or addition to a surgical approach in treating liver lesions.

Selective iliofemoral stent placement for complex pediatric cases: a decade of institutional experience.

Pediatric iliofemoral venous thromboembolism that is resistant to conventional treatments poses significant management challenges. Stent placement represents a potentially underutilized strategy in children when stenosis or thrombosis persists intraprocedurally or recurs postoperatively, despite treatments such as venoplasty, lysis, and thrombectomy. This study aims to report our institutional experience with iliofemoral stenting in 17 pediatric patients with recurrent iliofemoral venous thromboembolism or stenosis. We performed an IRB-approved retrospective review of pediatric patients (<18 years of age) who underwent iliofemoral venous stenting for recurrent stenosis or thrombosis between January 2012 and December 2022 at a single tertiary care institution. Patient demographics, risk factors for venous thromboembolism, presenting symptoms, and procedural characteristics were recorded. The primary outcome was stent patency rates at interval imaging follow-up. Seventeen patients with mean age of 14.6 years (range 7-17) and mean BMI of 27.7 were stented during the study period. Sixteen of 17 patients presented with evidence of May-Thurner anatomy. 14/17 patients presented with acute iliofemoral venous thromboembolism, 2/17 with chronic venous thromboembolism, and 1/17 with left lower extremity swelling without thrombosis. Seventy-three total angiographic procedures were performed, which included angioplasty, lysis, and thrombectomy, and 23 stent placements. Patients underwent an average of 3 procedures (range 1-9) over a mean of 2.8 months (range 0-17 months) prior to undergoing stent placement. Stents were deployed successfully in all patients. The median follow-up was 18 months (range, 1-77 months). Primary and secondary patency rates were 13/17 (76%) and 14/14 (100%) at 12 months and 12/17 (71%) and 14/14 (100%) at 24 months, respectively. In our experience of 17 patients, stent placement appears to be a durable option for children with iliofemoral venous thromboembolism following failure to establish vessel patency or development of recurrent thrombosis/stenosis postoperatively.

Transradial versus transfemoral access for treatment of HCC: a systematic review and meta analysis

Hepatic angiography procedures are essential in the treatment of hepatocellular carcinoma (HCC), with traditional transfemoral arterial (TFA) access being the traditional standard. Recently, transradial arterial (TRA) access has gained popularity, offering potential benefits. This study aims to conduct a systematic review and meta-analysis to compare TRA and TFA access in hepatic angiography oncologic procedures for HCC. The study investigates fluoroscopy time, radiation dose, patient preferences, and complications associated with each access method. A systematic review was performed using PRISMA guidelines, with 11 studies encompassing 2535 HCC procedures included. Statistical analysis was conducted using RevMan 5.4 software. Continuous outcomes were calculated as mean differences, and binary outcomes were measured as odds ratios. Patient preferences, procedural complications, and access site success rates were assessed. The meta-analysis revealed that there were no significant differences in fluoroscopy time, radiation dose, or contrast dose between TRA and TFA. Access failure rates were similar for both methods. However, the odds of adverse events, excluding access failure, were significantly higher for TFA, while the overall rate of complications was comparable. Patients strongly preferred TRA over TFA due to reduced hospital stay and post-procedure discomfort. This meta-analysis supports the use of TRA for hepatic angiography oncologic procedures for HCC with patient preferences in favor of TRA. Additional randomized clinical trials are encouraged to further evaluate the feasibility and benefits of both access sites.

The Complex Interplay of Variables in Extubation Decision-Making Following Pediatric Cardiac Surgery: A Narrative Review.

Pediatric cardiac surgery poses significant challenges in developing countries, where a considerable number of children require intervention for congenital heart disease (CHD). The utilization of endotracheal intubation and anesthesia is pivotal in conducting surgical or angiography procedures on patients with CHD exhibiting diverse anatomical and hemodynamic characteristics. The decision to extubate pediatric patients following cardiac surgery remains a crucial element of postoperative care. This article explores the complexities surrounding extubation decision-making in this population, emphasizing the critical role of surgical, physiological, and postoperative factors. Various preoperative and intraoperative factors influence the timing of extubation. Early extubation is increasingly prevalent, offering benefits like reduced length of stay and minimized drug exposure. Multidisciplinary collaboration and protocol-driven strategies contribute to improved extubation outcomes, emphasizing the need for a comprehensive approach in pediatric cardiac surgery. Future research can focus on the implementation and efficacy of standardized extubation procedures involving collaboration among healthcare experts.

Sex Differences in Fractional Flow Reserve Utilization.

Background: The literature review shows that female patients are more frequently underdiagnosed or suffer from delayed diagnosis. Recognition of sex-related differences is crucial for implementing strategies to improve cardiovascular outcomes. We aimed to assess sex-related disparities in the frequency of fractional flow reserve (FFR)-guided procedures in patients who underwent angiography and/or percutaneous coronary intervention (PCI). Methods: We have derived the data from the national registry of percutaneous coronary interventions and retrospectively analyzed the data of more than 1.4 million angiography and/or PCI procedures [1,454,121 patients (62.54% men and 37.46% women)] between 2014 and 2022. The logistic regression analysis was conducted to explore whether female sex was associated with FFR utilization. Results: The FFR was performed in 61,305 (4.22%) patients and more frequently in men than women (4.15% vs. 3.45%, p < 0.001). FFR was more frequently assessed in females with acute coronary syndrome than males (27.75% vs. 26.08%, p < 0.001); however, women with chronic coronary syndrome had FFR performed less often than men (72.25% vs. 73.92%, p < 0.001). Females with FFR-guided procedures were older than men (69.07 (±8.87) vs. 65.45 (±9.38) p < 0.001); however. less often had a history of myocardial infarction (MI) (24.79% vs. 36.73%, p < 0.001), CABG (1.62% vs. 2.55%, p < 0.005) or PCI (36.6% vs. 24.79%, p < 0.001) compared to men. Crude comparison has shown that male sex was associated with a higher frequency of FFR assessment (OR = 1.2152-1.2361, p < 0.005). Conclusions: Despite a substantial rise in FFR utilization, adoption in women remains lower than in men. Female sex was found to be an independent negative predictor of FFR use.

Emergency treatment of pelvic ring injuries: state of the art.

High energy pelvic injuries sustain significant mortality rates, due to acute exsanguination and severe associated injuries. Managing the hemodynamically unstable trauma patient with a bleeding pelvic fracture still forms a major challenge in acute trauma care. Various approaches have been applied through the last decades. At present the concept of Damage Control Resuscitation (DCR) is universally accepted and applied in major trauma centers internationally. DCR combines hemostatic blood transfusions to restore blood volume and physiologic stability, reduced crystalloid fluid administration, permissive hypotension, and immediate hemorrhage control by operative or angiographic means. Different detailed algorithms and orders of hemostatic procedures exist, without clear consensus or guidelines, depending on local traditions and institutional setups. Fracture reduction and immediate stabilization with a binder constitute the basis for angiography and embolization (AE) or pelvic packing (PP) in the hemodynamically unstable patient. AE is time consuming and may not be available 24/7, whereas PP offers a quick and technically easy procedure well suited for the patient in extremis. Resuscitative endovascular balloon occlusion of the aorta (REBOA) has also been described as a valuable adjunct in hemostatic non-responders, but merely constitute a bridge to surgical or angiographic hemostasis and its definitive role in DCR is not yet clearly established. A swift algorithmic approach to the hemodynamically unstable pelvic injury patient is required to achieve optimum results. The present paper summarizes the available literature on the acute management of the bleeding pelvic trauma patient, with emphasis on initial assessment and damage control resuscitation including surgical and angiographic hemostatic procedures. Furthermore, initial treatment of open fractures and associated injuries to the nervous and genitourinary system is outlined.

Selective postmortem arterial angiography of head and neck using digital x-ray or computed tomography: A practical and rapid method to identify vascular injuries.

Identification of vascular injuries is crucial for complete postmortem evaluation and understanding of trauma deaths by the Medical Examiner. Some vascular injuries are difficult to evaluate due to challenging anatomic locations, especially in the head and neck. Documenting injuries of the facial and vertebral arteries is challenging and necessitates time-consuming dissections that can create artifacts and disfigurement. In busy medical examiner offices with a significant number of traumatic injuries, finding a creative solution to employ reliable postmortem angiography is desirable. At the Office of the Chief Medical Examiner for the State of Maryland (OCME), we created and effectively implemented a selective angiography procedure using traditional indwelling Foley catheters and water-soluble barium swallow contrast to evaluate arterial injuries using either digital radiography or computed tomography imaging modalities. This technique and imaging interpretation can be performed by a medical examiner or forensic pathology fellow after basic technical training and basic radiology training. This study outlines the technique, methods, and utilization of the procedure and describes the findings of six deaths due to vascular lesions from different injury mechanisms and disease processes and describes the ease of implementation on a broader scale in busy Medical Examiner's offices.

Anemia to Median Nerve Palsy.

Mesenteric angina has a high mortality rate. Occlusion of the superior mesenteric artery is the most common cause. Increasingly, it is managed endovascularly instead of by open revascularization. Despite the lower risk of complications in minimally invasive procedures, it is important to be mindful of long-term sequelae of minor complications. Patient education regarding risks and complications is paramount for better clinical outcomes. The risks of transbrachial angiography procedures are low. Postprocedural vigilance for interventionists and written educational advice to patients are paramount in all minimally invasive endovascular procedures, especially because most of these patients with a complication require urgent operative correction.
